  • DRV8870: DRV8870 issues

    Part Number: DRV8870 Hello, We have an electronic board developed a few years ago that uses the DRV8870DDAR component. The old boards have not shown any issues. However, during a new production run, the new boards are not working correctly. It seems…

  • DRV8870: DRV8870: Current Regulation accuracy

    Part Number: DRV8870 Other Parts Discussed in Thread: DRV8251A , DRV8231A Hi Expert, Regarding the current‑limit feature of the DRV8870, the datasheet only specifies the op‑amp’s range as 9.4 V to 10.4 V, but it does not give the comparator’s accuracy…

  • DRV8870: The DRV8870 exhibits abnormal output at low temperatures.

    Part Number: DRV8870 hi expert When we were testing a circuit driven by DRV8870, we encountered an abnormal output situation in low-temperature environments. The circuit worked normally at normal temperatures. Around minus 20 degrees Celsius, the current…
